Hi! I am Carlos.

I am an computer scientist that worked for more than 20 years on online shops, . Since 2015 I was the head of the research and development department at Tabac Benden in Düsseldorf. In that function I created a multi-shop system, several brands and products and ultimately a profit-making business for the company.

Since 2021 I work for henworx GmbH & Co. KG. As a senior developer I wrote software with PHP, Laravel, React, React Native and if needed with Java.

I enjoy writing stable, clean software. Writing unit tests is not a burden, but a relief for me.

By the way: This website was also created to show a little bit of code to new employers. Check out this projects github page.

Yes this is a bit old-school, but this website is focussed on performance. Besides: What is the point in showing that someone can read the manual of a framework?
